System.Cron.Parser
Contents
Description
Attoparsec parser combinator for cron schedules. See cron documentation for how those are formatted.
import System.Cron.Parser main :: IO () main = do print $ parseCronSchedule "*/2 * 3 * 4,5,6"
Parsers
cronSchedule :: Parser CronSchedule Source #
Attoparsec Parser for a cron schedule. Complies fully with the standard
cron format. Also includes the following shorthand formats which cron also
supports: @yearly, @monthly, @weekly, @daily, @hourly. Note that this
parser will fail if there is extraneous input. This is to prevent things
like extra fields. If you want a more lax parser, use cronScheduleLoose,
which is fine with extra input.
cronScheduleLoose :: Parser CronSchedule Source #
Same as cronSchedule but does not fail on extraneous input.
crontab :: Parser Crontab Source #
Parses a full crontab file, omitting comments and including environment variable sets (e.g FOO=BAR).
crontabEntry :: Parser CrontabEntry Source #
Parses an individual crontab line, which is either a scheduled command or an environmental variable set.
